The Seventh Sister was a Mirialan member of the Inquisitorius who was tasked by Darth Vader to deal with the growing rebellion. Often working with the Fifth Brother, the two encountered and duelled with the Jedi Ahsoka Tano, Kanan Jarrus and Ezra Bridger on several occasions. The Seventh Sister was ultimately killed by the former Sith Lord Maul on Malachor.
